Trapped in a sinking submarine, two players must communicate through walkie-talkies to solve puzzles, complete tasks, navigate the depths, and escape before time runs out.

About

You're trapped in an old Cold War submarine. Your only goal: survive. Complete urgent repairs, manage limited resources, and keep the systems running. You can’t see each other. One misstep, one wrong call, and it’s all over.
Use your voice. Trust your partner. And don't run out of time.

You’ll never make it alone. Communicate through a crackling walkie-talkie. One speaks, the other listens - no exceptions. Relay codes, fix malfunctions, and guide each other through a maze of rust, steam, and shadows.
Forget clear sight. All you’ve got is each other’s voice. Keep it steady.

Time is not your friend. Each second wasted brings your doom closer - flooding compartments, failing engines, failing minds. Complete your tasks quickly. Stay calm under pressure. And if you mess up?
You’ll hear it. Feel it. Maybe even see it... before the ocean swallows you whole.

For a game centered around voice chat, you would think they would make it actually work and not be a broken mess. But then again, look at the developer's name. Can't recommend.
Fun hour long time sink. was good overall, fun idea mostly well executed asides from two things: one, once you finish a round win or lose you have to restart the entire game and two, the text on the console for the captain is incredibly hard to read quickly. I really enjoyed the game though and I'd return to it with a friend now and then if these issues were fixed or if the game was expanded upon more.

Sync Or Sink is a co-op game where one player acts as the captain and the other handles repairs aboard a failing submarine. The concept is simple, and it definitely creates some tense and funny moments. That said, the workload feels very uneven. The repair role is fairly straightforward: grab the right tools and fix what the captain tells you to fix. The captain, meanwhile, has to identify problems, locate rooms, manage resources, navigate the submarine, and somehow figure out when to fire torpedoes. The result is pure chaos, which I suppose is part of the fun. My friend and I spent most of our playthrough scrambling to keep the submarine alive while having absolutely no idea what was actually killing us. We eventually won with 1% health left after desperately spamming torpedoes randomly and hoping for the best. It's not a bad game, but it's also not one that kept us coming back after we cleared it. A decent choice for a chaotic evening with friends, especially if you're looking for something that tests communication more than skill.

Неплохая игра и задумка, повеселиться можно, но на один раз
l'idea del gioco era carina, ho anche visto dei gameplay online, ma giocando il caricamento è stato molto lungo (so che ho un dispositivo di bassa qualità ma credo che si possa ottimizare meglio il caricamento) e sono stati riscontrati vari bug (sia come comandante sia come ingegnere) tra qui segni delle porte che non apparivano per l'ingegnere e per il comandante (che non poteva neanche cambiarle), poi per il comandante non caricava i nemici, gli errori di sistema, i progressi dell'avanzata e infine non saliva l'acqua che funzionava da tempo. Comunque vedo positivamente questo gioco e spero che il tutto possa essere sistemato.
Wondrous little game. A bit unintuitive at times, but easy enough to get the hang of after a few trial runs. From playing the Engineer and receiving orders to fix things or load torpedoes, while communicating with the Captain for them to open specific bulkheads for you, to playing Captain and being in command of piloting the sub, and being able to diagnose issues in the submarine and their solutions to report to the Engineer. Both roles are super fun to play and offer unique challenges. Also if you are bad at communicating with your friend, this will straighten that out real fast. And there can be some seriously clutch moments, like how I was captaining the sub yesterday, dealt with an enemy sub, and very quickly had another on my radar. My friend had just fixed something in the Engine room, so the torpedoes were behind a locked door. I panicked, but nevertheless through speedy communication, me opening a bulkhead, and my friend absolutely booking it, he loaded a torpedo, I fired it, and the enemy sub was obliterated. So so very fun. I can hardly wait to see how this game shapes up through early access and onward. If it sounds interesting, get a friend and try it out! It's free, after all.
ИГРА ТОП ЗА СВОИ ДЕНЬГИ

didnt work in multiplayer. we couldn't use the comms, we got stuck in the map multiple times, and im 90% sure there wasnt a breach anywhere
